ABSTRACT OF DISSERTATION
|
|
In wireless communication systems, it is well known that the instantaneous received signal power is a random variable that follows a given distribution. The randomness mainly stems from effects such as multipath fading, shadowing, and interference. Several distributions have been used in the literature to characterize the fading phenomenon. However, as new radio technologies emerge, the known distributions are deemed insufficient to fit simulated and measure data. Subsequently, as the wireless industry moves onto the fifth generation (5G), newer distributions are being proposed to well represent the received signal for new wireless technologies, including those operating in the millimeter-wave (mmWave) band. These are mainly application specific. Secondly, an explosion of new radio technologies and devices operating in the same limited radio spectrum is expected, which will thrust interference modeling in dense networks to the forefront due to overcrowding. Thirdly, the classical distributions used to model the received signal do not account for the fundamental inherent mobility feature for emerging radio technologies such as avionics systems (eg. drones). Consequently, in this dissertation, we propose the use of a unifying distribution, the Fox's H-function distribution, with subsume ability to represent several traditional and future distributions, as a statistical tool to evaluate performance of wireless communications systems. Additionally, two interference models, one with a fixed number and the other with a random number of interferers, are considered to derive interference statistics and further utilize the results to analyze system performance under the effect of interference. Finally, we extend the classical distributions to include the mobility regime for several wireless network topologies and perform network analysis. The analytical results are validated using computer simulations.
